Wind turbines are used to generate electricity from the kinetic power of the wind. Historical they were more frequently used as a mechanical device to turn machinery. There are two main kinds of wind generators, those with a vertical axis, and those with a horizontal axis. Wind turbines can be used to generate large amounts of electricity in wind farms both onshore and offshore. So wind energy can be produced form wind through using wind turbine, because of its cleanness and low cost, it is widely used in our daily life.

Wind energy is undoubtedly one of the cleanest forms of producing power from a renewable source. There is no pollution, there is no burning of fossil fuels, and unless something very drastic happens, you don’t run out of wind. But it’s not like you can erect a wind turbine anywhere and it will start generating power for you. There are lots of factors that can make an impact on the amount of energy you can generate out of wind.

l Wind

It being a wind turbine, its output first most depends on the wind. Both the speed and force of the wind can be deciding factors. The more wind speed and force you have got, the greater is the amount of power your wind turbine generates. Different regions have different wind speeds. You can gather the available wind dynamics data and using a model like Webull Distribution you can calculate how effective the wind of a particular region is going to be.

l Height

Places of higher altitudes have more wind due to various atmospheric factors. Besides, at higher places there is less obstruction from the surrounding hills, trees and building. In fact the height is so important that alternative energy scientists and engineers are trying to use kites (due to the heights they can easily reach) to tap the wind power.

l Rotor

The amount of energy produced by your wind turbine is proportional to the size of the rotor used, when all other factors have been taken into consideration. A bigger rotor certainly generates more power. Although it may cost more, in the long run, whenever you are getting a wind turbine erected, go for a big a rotor as possible.

ABB will promote new series of wind generator with slip ring, this new product increases its performance through reinforcing the structure of rotor and modular design, and it will show up at 2010 Asia wind energy meeting which will be held in Beijing during the end of June.

In June of 2010, ABB enterprise which leads the electric and automatic technology areas in the world promotes new series of generator with slip ring in it, through introducing global double-feedback concept, the research of new style generator is based on method which is used by the main turbine machine producer since 1997, and the method is reliable and have high efficiency which is used all over the world.

The new style generator’s power range is between 1.5 and 2 MW, through using modular design, the device has strong match, and can be used at different kinds of double-feedback turbine generators which are currently popular, so it is perfect choice for the update of devices in wind turbine generator group. The production base can product generators with power, at the same time, ensure the quality and quantity, and the connection interface which is used to connect different turbine generators can be determined according to the demand of customers. We offer customers air cooling method and water cooling method, specially produce generators which the frequency is 60Hz for American market.

The design of New style generator’s rotor has acquired patent in America, the bottom of winding has the optimized supporting ring, which can bear high speed working condition, and can cool the device better and fast.

ABB enterprise is the reliable supporter of wind generator, has a good reputation, and is famous for producing generator, converter, all kinds of electric components in wind generating system. In the past thirty years, ABB enterprise has produced approximate 30000 wind generators. The advantage of this new wind generator is based on the experience of 100 years’ effort on manufacturing better generator.

This new generator will show up at this June in Beijing, at the same time, it will be sold to all over world in shanghai ABB enterprise.

Electrical power generated at the floating Air Rotor is transferred down the tether to ground level equipment. Depending on size of the Air Rotor, power is sent to users ranging from campers to large power grids. Helium (an inert non-flammable lighter-than-air gas) sustains the Air Rotor which ascends to an altitude for best winds. No towers or heavy foundations are necessary and sizes range from small “backpack” models to large megawatt generating devices.

All competing wind generators use bladed two-dimensional disk-like structures and rigid towers. The Magenn Power Air Rotor system is a closed three-dimensional structure (cylinder). It offers high torque, low starting speeds, and superior overall efficiency thanks to its ability to deploy higher. The closed structure allows Magenn Power to produce wind rotors from very small to very large sizes at a fraction of the cost of current wind generators.

This electrical energy is transferred down the tether to a transformer at a ground station and then transferred to the electricity power grid. Helium (an inert non-reactive lighter than air gas) sustains the Air Rotor which ascends to an altitude for best winds and its rotation also causes the Magnus effect. This provides additional lift, keeps the device stabilized, keeps it positioned within a very controlled and restricted location, and causes it to pull up overhead rather than drift downwind on its tether.

 A wind power generator is a machine that uses wind energy to produce electrical energy. It captures the winds power and converts it into mechanical energy that rotates the blades of a motor to produce electrical energy. Wind generators help produce thousands of megawatts of electricity. They are also a very popular power solution for individual farms. They are perfect for large areas with good wind speed.

Wind generators have been in use for a long time in the form of windmills or wind turbines. Years ago, when electricity was not invented, wind turbines were used to pull boats and pump out water.Surprisingly the first use of the wind machines was for grinding grains as early as 200 B.C in Persia. It was also introduced in the prosperous and powerful Roman Empire in 250 A.D. The year 1900 saw the maximum number of windmills being used in Denmark. Almost 2500 windmills were installed to provide the much needed mechanical load to pumps and gave a peak power of 30MW.

Even now, the terms, wind generator, windmill, and wind turbine are used to refer to the same device.

What are the advantages of using a wind generator? The advantages of a wind generator are many. Let’s look at a few of them.

Environment-friendly: Wind power generators prove to be environment-friendly in two ways:

They do not emit harmful gases in the atmosphere nor do they leave any harmful residual component.

They do not use any fuel to produce electricity, hence helping the cause of the environment.

Power-saver: Wind generators are an alternative power solution. They do not use any non-renewable sources of energy, thus helping in times of energy crisis.

Economical: Though the initial cost of setting up a wind generator seems high, the cost of generating electricity in the long run becomes nil. So basically, you will be getting electricity absolutely free after a few years.

Independent option: Wind generators do away with the dependence on power plants and the government for electricity. With a wind generator in your land, you have your own power plant for life.

24/7 power: With wind generators, you can say bye to power outages forever. You will get continuous, uninterrupted power supply for your entire house and land.

Power storage: A wind generator also allows you to store power for use later. This feature makes it an amazingly lucrative power solution.

With more and more fuels getting wasted and used, there are very few options remaining. Bio-fuel is one of the options and to add to it is the use of solar panels for driving motors and making electricity. The third option is harnessing the wind power. So build a wind generator today and do something good for your home and for our environment.
